ANCHOR DEVICE Filed July 22, 1929 Patented June `21, 1932 UNITED STATES 'PATENT orifice ELBERT E. FORREST, OF GARY, INDIANA, ASSIGNOR T0 LINE MATERIAL COMPANY, OF SOUTH MILWAUKEE, WISCONSIN, A CORPORATION OF DELAWARE ANCHOR DEVICE Application filed J'uly 22,

This invention relates to certain new and useful improvements in anchor devices and refers more particularly to provide means of attachment for line iixtures to brick walls and the like.

Devices of this type heretofore in use, very often pulled out upon the application of stress, especially when applied to new buildings where the mortar was still green, as their' construction was such that only a relatively small portion thereof was expanded to grip the walls of the recess in which the device was mounted. Another objectionable feature of devices of this type heretofore in use, was that they became loosened whenever the fixture which they mounted was removed.

The present invention obviates these objections and has as one of its objects the provision of an anchor device which tends to expand bodily, that is, the application of outward stress tends to move the entire device laterally to thus increase the intimacy of contact throughout the entire length of the device and insure positive binding to prevent r its being pulled out.

Another object of this invention resides in the provision of an anchor device of the character described which is more easily applied and which when in position does not become loosened when the fixture it supports is removed.

A further object of this invention resides in the improved construction of an anchoring device of the character described which is securable in a recess formed between Vthe bricks of a brick wall or the like by merely driving a wedge into the recess between the device proper and the adjacent wall of the recess.

And a still further object of this invention resides in a provision of a novel construction Y for anchoring devices of the character described which co-operates with a wedge driven into the recess between the inclined face and the adjacent wall of the recess in which the device is secured to securely hold the same against withdrawal and wherein an attaching screw carried by the device projects beyond the surface of the wall to provide to a device adapted f 1929.

means for securing line fixtures or the like to the wall.

With the above and other objects in view which will appear as the description proceedS, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafterrdescribed and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim. In the accompanying drawing, I have illustrated one complete example -of the physical embodiment of cording to the best mode I have so far devised for the practical application of the principles thereof, and in which r Figure l is a view partly in elevation and partly in section illustrating an anchor device constructed in accordance with my invention secured in a recess formed between two adjacent bricks of a brick wall and having an insulator attached thereto; and

Figure 2 is a perspective view of my improved anchoring device and the wedge used to secure the same in position.v

Referring more particularly to the accompanyingdrawing the numerals 5 and 6 represent two adjacent bricks of a brick wall betica tween which, in the present instance, my improved anchoring device is adapted to be secured.v The device proper consists of a body member' 7 formed of lead or other suitable relatively soft metal in which an attach-V ing screw 8 having a head 9 is embedded with its threaded end 10 extending beyond its forward end. As best illustrated in Figure 2 the body member is substantially rectangular in cross section and has fiat 11 is inclined downwardlyvand forwardly.

To secure the device to the wall a recess l2 is formed between the bricks 5 and 6, by removing some of the mortar 13, to freely receive the body member, and a wedge 14Y is driven between the inclined face l1 of the body member and the acent wall l5 of the recess. The wedge is preferably of a width equal to that of the body member and has its forward end V shaped to facilitate drivingU Tfmy invention constructed acsides one of which i and when driven home rigidly secures the body member against detachment with the threaded end of its attaching screw extended beyond the surface of the wall.

Any desired fixture may then be fixed to the wall by Ahaving a portion thereof threaded onto the attaching screw and in the present instance an insulator 16 of conventional construction is secured thereto by having an internally threaded sleeve 17 lined in a recess '18 in the insulator threaded onto the extended end of the attaching screw as clearly illustrated in Figure l.

During the application ofthe insulator it is evident that outward stress will be applied to the screw 8 and consequently to #the body member 7. This outward stress7 however, merely increases the intimacy of contact between the body member and the wedge and 'the adjacent walls of the recess 12, as it increases the combined thickness of the body member and the wedge through the coaction between the inclined face of the body member and the wedge. To insure the wedge remaining in the position in which it is driven, its side which engages the wall `of the recess is preferably serrated as at 19, and it will be noted that the expansion which takes place upon the application of outward stress acts throughout the entire length of the wedge and the body member and in as much as the sides of the body member are flat an-eXceptionally strong grip is obtained.

From the foregoing description taken in connection with the accompanying drawing it will be readily apparent to those skilled in the art of which the invention of the character described appertains that I have provided an improved construction for anchor devices wherein greater strength is obtained and wherein the device does not become loosened when the xture it supports `is removed.

W'hat I claim as my invention is:

In an anchor device of the character described, adapted to be secured in a recess formed in a support, comprising a flatsided body member formed of relatively soft metal and insertable into the recess, a headed attaching screw embedded in the body member with its threaded end projecting therebeyond and a flat sided wedge, which, when driven into the recess between one wall thereof and the body member secures the body member in the recess in such a manner that outward stress applied to the attaching member tends to move the body member laterally through the entire length into more intimate Contact with the recess wall.

In testimony whereof I have hereunto affixed my hand.
